Much of the research on gut bacteria has focused on the large intestine, however a new study shows how the typical calorie-dense western diet can induce expansion of microbes in the small intestine that promote the digestion and absorption of high-fat foods.
Several studies have shown that these bacteria can multiply within 24 to 48 hours in the small bowel in response to consumption of high-fat foods. The findings from this work suggest that these bacteria facilitate production and secretion of digestive enzymes into the small bowel.
Those digestive enzymes break down dietary fat, enabling the rapid absorption of calorie-dense foods. Concurrently, the bacteria release bioactive compounds. These compounds stimulate the absorptive cells in the intestine to package and transport fat for absorption. Over time, the steady presence of these bacteria can lead to over-nutrition and obesity.
The study was published April 11, 2018 in the journal Cell Host and Microbe. It was established to find out if microbes were required for digestion and absorption of fats.*
The most important takeaway overall is the concept that what people eat, their daily diet, has a profound impact on the abundance and the type of bacteria that’s harboured in the gut. These microbes directly influence the metabolism and the propensity to gain weight on certain diets.
Although this study was very preliminary, the results suggest that people could use pre- or probiotics to enhance nutrient uptake for people with malabsorption disorders, such as Crohn's disease, or could test novel ways to decrease obesity.
